Soil Erosion Modelling

Soil erosion is one of the main problems affecting land resources throughout South Africa. This is especially evident in Ukhahlamba Drakensberg Park and buffer zone areas where poor agricultural practices and overgrazing have resulted in massive losses of topsoil, the creation of huge dongas, and a loss of income earning potential to the local people.

In 2010 the African Conservation Trust  received funding from the National Lottery Distribution Trust Fund (NLDTF) to do gully rehabilitation in the Upper uThukela catchment area. The project employed local teams to rehabilitate gullies using manual techniques such as stone packing and planting Vetiver grass to stabilise the soil. The project was a great success, but there is still a huge amount of rehabilitation work required.

The NLDTF has provided funding for the University of KwaZulu Natal Foundation Trust  and ACT  to implement a project to create a soil erosion model for the Drakensberg region. The resulting model will show areas that are likely to be affected by soil erosion so that pre-emptive action can be taken. A model of the carbon load in the soil will also be developed which will benefit local communities through a proposed payment for environmental services.
